In an important experiment, a radioactively labeled bacteriophage was allowed to infect bacteria. In a first trial, the phage co

ntained radioactive DNA, and radioactivity was detected inside the bacteria. Next, phage containing radioactive protein was used, and the radioactivity was not detected inside the bacteria. These experiments led to the conclusion that __________.

Answer:

The correct answer will be- DNA acts as the genetic material of the phage

Explanation:

A bacteriophage is a virus which infects the bacteria by inserting its genetic material into the host cell and using its DNA replication machinery to replicate or divide.

In the given question, when DNA was radiolabeled, radioactive DNA was observed in the host cell but when the protein was radiolabeled, it was not observed in the host cell as the molecule to be inserted in the host cell is the DNA (genetic material) to be replicated.

Thus, DNA acts as the genetic material of the phage is the correct answer.

What are the implications of using ergogenic aids? Discuss pros and cons of these substances
NNADVOKAT [17]

Answer:

Ergogenic aids, as the latter word (aid) implies, is any substance, drug, device, taken by individuals with the aim of increasing the capacity for work output through eliminating fatigue and improving recovery from tedious tasks. Some examples of ergogenic aids include ephedrine, caffeine, creatine, anabolic steroids. They are used for the treatment of some health problems and they are also used by athletes (some are banned substances in some sports).

Question: What are the implications of using ergogenic aids

Answer: Is discussed in the pros and cons section of using ergogenic aids below

Pros of using ergogenic aids

1. It can be used to treat some health conditions.

2. Ergogenic acids, for example, steroids increase muscle activity during exercise and decrease fatigue.

3. Increase muscle mass, increase bodily strength and power .

4. Gives a competitive edge to individuals who use it over others in sports.

Cons of using ergogenic aids

1. High doses could have an adverse effect on consumer health which include: central nervous system and kidney damage.

2. It can increase the level of aggression in consumers which is not good especially in sports.

3. Anabolic steroids  could also affect the potency of sperm cells, sperm production in males, and could also disrupt the menstrual cycle in females.

How does the HaeIII enzyme discriminate between the C-G polymorphism in the TAS2R38 gene?
valkas [14]

Answer;

-HaeIII cuts at the sequence GG:CC which is found at nucleotide 143-146 of the TAS2R38 gene. A non-taster alley changes the sequence at position 145 from a C to a G. This makes the gene no longer recognized by the restriction enzyme.

Explanation;

-Restriction enzymes recognize and make a cut within specific palindromic sequences, known as restriction sites, in the genetic code. This is usually a 4- or 6 base pair sequence.

For example; HaeIII is a restriction enzyme that searches the DNA molecule until it finds this sequence of four nitrogen bases.

Once the recognition site was found HaeIII could go to work cutting (cleaving) the DNA
